Microdajidae is a family of crustaceans belonging to the class Tantulocarida. [1] The family was previously place in class Hexanauplia. [2]
Genera: [1]
A third genus, Xenodactylus , is sometimes placed in the family, but its status is doubtful. [2]
Chlorophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it is a highly paraphyletic group of all the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it is the sister clade of the streptophytes/charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants, green algae contain chlorophyll a and chlorophyll b and store food as starch in their plastids.
The bourgeoisie is a class of business owners and merchants which emerged in the Late Middle Ages, originally as a "middle class" between peasantry and aristocracy. They are traditionally contrasted with the proletariat by their wealth, political power, and education, as well as their access to and control of cultural, social and financial capital.
The middle class refers to a class of people in the middle of a social hierarchy, often defined by occupation, income, education, or social status. The term has historically been associated with modernity, capitalism and political debate. Common definitions for the middle class range from the middle fifth of individuals on a nation's income ladder, to everyone but the poorest and wealthiest 20%. Theories like "Paradox of Interest" use decile groups and wealth distribution data to determine the size and wealth share of the middle class.
Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a class in superclass Multicrustacea. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.
Upper class in modern societies is the social class composed of people who hold the highest social status, usually are the wealthiest members of class society, and wield the greatest political power. According to this view, the upper class is generally distinguished by immense wealth which is passed on from generation to generation. Prior to the 20th century, the emphasis was on aristocracy, which emphasized generations of inherited noble status, not just recent wealth.
Christopher Barton Adkisson was an American professional wrestler, best known under the ring name Chris Von Erich of the Von Erich family.
Kerry Gene Adkisson, better known by his ring name Kerry Von Erich, was an American professional wrestler. He was part of the Von Erich family of professional wrestlers. He is best known for his time with his father's promotion World Class Championship Wrestling (WCCW), where he spent eleven years of his career, and his time in World Wrestling Federation (WWF), under the ring name the Texas Tornado. Adkisson held forty championships in various promotions during his career. Among other accolades, he was a one-time NWA World Heavyweight Champion, four-time WCWA World Heavyweight Champion, making him an overall five-time world champion and one-time WWF Intercontinental Champion.
Kevin Ross Adkisson is an American retired professional wrestler, better known by his ring name, Kevin Von Erich. A member of the Von Erich family, Von Erich is best known for his appearances with his father's World Class Championship Wrestling promotion. He is a one-time world champion, having held the WCWA World Heavyweight Championship.
Michael Brett Adkisson was an American professional wrestler under the ring name Mike Von Erich. His four brothers, David, Kerry, Kevin and Chris, also wrestled. He was the son of longtime Texas wrestler and wrestling promoter Fritz Von Erich and a member of the Von Erich family.
Cumoniscidae is a family of crustaceans in the class Tantulocarida, classified under the superclass Multicrustacea. The family was previously known as Deoterthridae, but Cumoniscidae was determined to be senior subjective synonym.
Pancrustacea is the clade that comprises all crustaceans, including hexapods. This grouping is contrary to the Atelocerata hypothesis, in which Hexapoda and Myriapoda are sister taxa, and Crustacea are only more distantly related. As of 2010, the Pancrustacea taxon was considered well accepted, with most studies recovering Hexapoda within Crustacea. The clade has also been called Tetraconata, referring to having four cone cells in the ommatidia. This name is preferred by some scientists as a means of avoiding confusion with the use of "pan-" to indicate a clade that includes a crown group and all of its stem group representatives.
The Von Erich family is an American professional wrestling family. Originally from Texas, their actual surname is Adkisson, but every member who has been in the wrestling business has used the ring name "Von Erich," after the family patriarch, Fritz Von Erich. Jack took on the name as part of his wrestling gimmick as he originally portrayed a Nazi heel, hence his use of a German name.
The social structure of the United Kingdom has historically been highly influenced by the concept of social class, which continues to affect British society today. British society, like its European neighbours and most societies in world history, was traditionally divided hierarchically within a system that involved the hereditary transmission of occupation, social status and political influence. Since the advent of industrialisation, this system has been in a constant state of revision, and new factors other than birth are now a greater part of creating identity in Britain.
In biology, taxonomic rank is the relative level of a group of organisms in an ancestral or hereditary hierarchy. A common system of biological classification (taxonomy) consists of species, genus, family, order, class, phylum, kingdom, and domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics.
Crustaceans are invertebrate animals of the subphylum Crustacea, a large, diverse group of mainly aquatic arthropods including decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans.
The biological systematics and taxonomy of invertebrates as proposed by Richard C. Brusca and Gary J. Brusca in 2003 is a system of classification of invertebrates, as a way to classify animals without backbones.
The taxonomy of the animals presented by Hutchins et al. in 2003 in Grzimek's Animal Life Encyclopedia is a system of classification which covers all the metazoans, from phyla to orders.
The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of multicrustacea is the class Malacostraca.
Doryphallophoridae is a family of crustaceans belonging to the class Tantulocarida. The family was previously placed in class Hexanauplia.
